Black screen flickering

[Canned Beef]

i have the acer wmr headset, its been working fine for some time, but recently it started flickering black, not black pixels, but off, in steamvr and wmr home. ive tried just about everything, i only have 1 usb 3 on my laptop. sometimes it works for a long time, sometimes it freaks out instantly, it will brighten and flicker to black and sometimes come back. if i try to reboot wmr portal it simply stays black, reboot or not. if i replug it works again for a little while. no drops, no bumps, only had it for under 2 weeks. no tugged ports or anything, new laptop, no windows updates, steam etc. tried betas and non betas of wmr steamvr and steamvr. i have no idea what it could be, nothing happened, it simply stopped working as intended, no updates at the time that could trigger it. it worked and now it doesnt reletively speaking. also reinstalled wmr software and drivers, updated graphics driver, tested insider builds. tested boundary on and off, seated and roomscale. i could test another usb if i get a usb c 3.1 to usb 3.1, although with it working flawlessly beforehand i have no idea what could cause the port to go bad or start supplying insufficient power in under 2 weeks.

This problem was actually asked in the WMR subreddit too, imma just drop a link here, it didn't really help me, but i didn't contact that Microsoft engineer helping the people there out yet.

Just leave a comment there, maybe he can help you, seems to be a Windows bug with the location services as far as I can read it out.

Hello,

like many others (check reddit, MS Forum, ...) i have the black flickering Issue. This ist nearly all the time in random time slots. After some playing (around half an hour) very often screen turns black and doesn't come back. Only when i Plug and unplug the WMR Headset. When Mirroring i can see that game is still working and Headtracking + Controllers are working too.
I tried different Mainboard USB Ports, a USB 3 PCI Card, different cables (with and without 1.5 m Cabel extension), different drivers (GPU, Mainboard, ...), reinstalled WMR, ... .
I have a 1080, so specs should not be the problem.
Does anyone who had this issue solved it?
It's so annoying.

@s.d1 Try to contact the user Geoff on the subreddit I linked in a earlier reply of mine, he needed 2 days to find my problem.

It sounds like this is not specific to SteamVR and also happens in the Cliff House. That's helpful information to make sure to include in your Feedback Hub entry. Thanks!

I solved it by myself. After rearranging my whole PC (got a new desk) and reconnecting everything it now works. The only thing is different now, is a now disconnected USB Port 3 Hub that before wasn't even connected with BT or WMR. But somehow it interfered with the Headset.
